weakness

"God will empty out all that thou hast before he will put his own into thee; he will first clean out thy granaries before he will fill them with the finest of the wheat. The river of God is full of water; but not one drop of it flows from earthly springs. God will have no strength used in his battles but the strength which he himself imparts. Are you mourning over your own weakness? Take courage, for there must be a consciousness of weakness before the Lord will give thee victory. Your emptiness is but the preparation for your being filled, and your casting down is but the making ready for your lifting up."

"When I am weak then am I strong,
Grace is my shield and Christ my song."

-C.H. Spurgeon
